PLAlTER-BLADE.

SPECIFICATION forming part of Letters Patent No. 473,303, dated April19, 1892.

Application filed December 28, 1891. Serial No. 416,306. (No model.)

To all whom it may concern:

Be it known that I, CHARLEs 0. Phantom, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Plaiter- Blades; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to .which it pertains tomake -to receive the goods acted upon between them and between theplaiter-blades proper and the goods, whereby only the points of theblades come in contact with the goods, and are automatically made torecede from the goods by the shields, thus allowing them to engage withthe goods positively as they move forward, but be disengaged therefromwhen they reach the end of their stroke and begin to move back.

In the drawings, Figure l is a detached perspective view of shields andplaiter-blades which embody my invention complete, showing them inoperative position. Fig. 2 is a plan View of one of the shields. Fig. 3is a plan view of one of the plaiter-blades proper.

,G indicates hangers, which are connected in any suitable manner to areciprocating means of the plaiti ng-machine, as will be readilyunderstood, to be moved back and forth therewith. Secured to thesehangers at their inner sides are the plaiter-blades, which have theirouter ends slotted to form any desired numberof prongs D,as shown.Secured, also,

to the hanger inside of the blades 0 are the shields A, which consist ofblades, as shown, which are preferably perfectly or substantiallystraight and. parallel. These shields are placed to receive the goods tobe operated upon between them, and thus serve to separate the bladesfrom the goods, except at their pronged ends, which latter pass througha corresponding number of slots or openings B made in the shields. Theends of the blades are made to pass through the slots B and engage thegoods, as will be understood, and the blades are formed of any suitablespring metal, in order to allow the prongs to recede or be forced backthrough the slots, as will presently appear. The goods being operatedupon, passing between the shields, are engaged by the outer ends of theblades only, which extend through them, so that as the blades andshields are reciprocated the outer end of one shield disengages theteeth D of the other shield from the goods by engaging therewith as itpasses overit, causingthe teeth to recede. In this manner the teeth ofeach blade are made to positively disengage the goods at the proper timeand are held out of engagement therewithby the shields.

While I here show the ends of the blades provided with several prongs,it will be understood that they may merely have their ends reduced insize and passed through a corresponding opening in the shields, ifdesired, without departing from the spiritof my invention, and I do not,therefore, limit myself to the precise construction here shown, for itmay be varied and the object accomplished-viz., one blade disengagedfrom the goods by the shield of the other blade. This constructionrelieves the goods from all pressure, while at the sametime the blade isallowed to engage the goods as firm and rigid as the shield itself assoon as any forward movementis made and pressure brought upon theirfronts.

The shields may be either rigid or elastic and made from any desiredmaterial, While the blades are madeelastic in order to readily recedethrough the shields and to pass back through them to engage the goods.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. A plaiter-blade having prongs forming teeth, combined with a shieldrigidly secured to the blade and moving therewith, the shield beinglonger than the blade and provided with openings through which the teethof the blade pass, substantially as described.
